Witryna12 lip 2024 · If the pitch is expressed in units of semitones, it's 12 times that base-2 logarithm. The pitch has to be relative to a standard pitch. For MIDI, the pitch is p ( t) = 12 log 2 ( f 0 ( t) 440 H z) + 69 and is in units of semitones with Middle C having a pitch of 60. Share Improve this answer Follow edited Jul 13, 2024 at 21:33
